Instead of having to manually edit these over and over, lets just drop
the comments that no one will miss.

The first time to write a useful and valid STAT table actually!

I’m getting error "C2467: illegal declaration of anonymous 'union'"
otherwise, and the rest of AFDKO in not building with this option.

No idea what is the difference between Reuse and Free (presumably when
makeotf was used as a library to avoid re-allocating dynamic arrays?).
Implement it anyway for completeness sake, though it does not seem to
make any practical difference.

Move ElidedFallbackName errors to featgram.g so that line number i
sprinted as well, and improve the wording of other errors.

Make sure the name ID used actually exists in the name table.

They were separate in anticipation of name id sharing, but this is not
going to happen at the moment.

Describing the syntax, not attempt at describing what the table does.
